	gcc            : ChangeLog emit-rtl.c expr.c 

Log message:
	Add CONST1_RTX (vector mode) support.
	* emit-rtl.c (gen_const_vector): Renamed from gen_const_vector_0.
	Add integer argument named constant.  Use const_tiny_rtx instead of
	CONST0_RTX.
	(gen_rtx_CONST_VECTOR): Rewrite to handle checks for both CONST0_RTX
	and CONST1_RTX.
	(init_emit_once): Fix users of gen_const_vector.  Set CONST1_RTX for
	vector types.
	* expr.c (const_vector_from_tree): Call gen_rtx_CONST_VECTOR instead
	of gen_rtx_raw_CONST_VECTOR.
